Summary

This trial tests niraparib alone and with other treatments in patients with ovarian, fallopian tube, or primary peritoneal cancer. It aims to see if stopping cancer cells from repairing their DNA can help treat these cancers. Niraparib is a medication taken by mouth and is approved for use in patients with recurrent ovarian, fallopian tube, or primary peritoneal cancer who have responded to previous treatments.

Who is the study for?
This trial is for women aged 18 or older with high-grade recurrent ovarian, fallopian tube, or primary peritoneal cancer. They must have measurable disease and be in good enough health to participate (ECOG status of 0-2). Pregnant or breastfeeding women can't join, and participants need adequate organ function and not be on certain medications.
What is being tested?
The study tests the effectiveness and safety of niraparib alone or combined with other treatments like TSR-042, Bevacizumab, Paclitaxel, Carboplatin in treating ovarian cancer. Cohort A focuses on those with recurrent cancer; Cohort C includes newly diagnosed patients.
What are the potential side effects?
Possible side effects include fatigue, nausea, blood cell count changes leading to increased infection risk or bleeding problems. There may also be reactions related to infusions and potential liver issues.

Trial Design

3Treatment groups
Experimental Treatment
Active Control
Group I: Cohort C: Arm 2: Participants receiving neoadjuvant NiraparibExperimental Treatment2 Interventions
Participants are expected to receive 1 run-in cycle (up to 5 weeks) of carboplatin-paclitaxel during pre-screening. After confirmation that the tumor is HRd, participants will be randomized to three 21-day cycles of neoadjuvant niraparib therapy. After IDS, all participants will receive up to three 21-day cycles of adjuvant platinum-taxane doublet chemotherapy (and optional bevacizumab for participants deemed high-risk; third cycle is optional) followed by niraparib (and optional bevacizumab or bevacizumab biosimilar for participants deemed high- risk) maintenance treatment.
Group II: Cohort A: 1-2 prior lines of therapy (TSR-042, Bevacizumab, and Niraparib)Experimental Treatment3 Interventions
PARP Inhibitor-Naive Platinum-Resistant Ovarian Cancer Treatment Cohort with TSR-042, Bevacizumab, and Niraparib. TSR-042 administered 500 milligrams (mg) on Day 1 every 3 weeks (Q3W) for 4 cycles (each cycle is 21 days), followed by 1000 mg every 6 weeks (Q6W) beginning on Cycle 5 Day 1 until progressive disease (PD) or toxicity. Bevacizumab administered 15 milligram per kilogram (mg/kg) every 3 weeks for up to 15 months. Niraparib 200 or 300 mg per day until PD or toxicity.
Group III: Cohort C: Arm 1: Participants receiving platinum plus taxaneActive Control4 Interventions
Participants are expected to receive 1 run-in cycle (up to 5 weeks) of carboplatin-paclitaxel during pre-screening. After confirmation that the tumor is homologous recombination-deficient (HRd). Participants will then be randomized to three 21-day cycles of platinum-taxane doublet chemotherapy (carboplatin plus paclitaxane). After interval debulking surgery (IDS), all participants will receive up to three 21-day cycles of adjuvant platinum-taxane doublet chemotherapy (and optional bevacizumab for participants deemed high-risk; third cycle is optional) followed by niraparib (and optional bevacizumab or bevacizumab biosimilar for participants deemed high- risk) maintenance treatment.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
The most common treatments for ovarian tumors include PARP inhibitors, chemotherapy, and angiogenesis inhibitors. PARP inhibitors, such as Niraparib, work by blocking the PARP enzyme, which helps repair DNA damage in cells. This is particularly effective in cancer cells with BRCA mutations, leading to cell death. Chemotherapy, using agents like carboplatin and paclitaxel, targets rapidly dividing cells, causing DNA damage and cell death. Angiogenesis inhibitors, such as bevacizumab, prevent the formation of new blood vessels that tumors need to grow. These treatments are crucial for ovarian tumor patients as they target different aspects of tumor growth and survival, improving treatment efficacy and patient outcomes.
